Coverage of named threat actors and intrusion sets examines reported incidents, infrastructure, disruption, and defensive guidance.
Search across headline titles and summaries.
Background for this topic.
Coverage under this tag concerns a named threat actor or intrusion set: an individual, group, or organized operation assessed to be responsible for malicious cyber activity. Reports may describe incidents, malware, attack infrastructure, disruption efforts, or analyst assessments. Attribution is often provisional, so actor names and reported links should be treated as intelligence judgments rather than established identity, nationality, sponsorship, or motive.
For defenders, such reporting can help connect incidents and prioritize monitoring, but indicators and techniques may be reused or become obsolete. Validate reported infrastructure, hashes, and behaviors against local telemetry; use confirmed weaknesses to guide vulnerability remediation and access controls. If activity is suspected, preserve relevant logs and evidence, contain affected accounts or systems, and coordinate investigation without relying on an actor label alone.

TrendAI™ Research analyzed over 200 Gemini CLI session logs showing how a Russian-speaking threat actor used AI to run a live botnet, finishing a full C&C migration in six minutes while doing just 11% of the work himself.
We tracked a cryptocurrency-mining campaign exploiting CVE-2026-33017, which revealed how threat actors are now scanning exposed AI application infrastructure for their next foothold.
Cybercriminals hijacked Google Ads searches for popular AI developer tools to funnel over 2,000 victims toward malicious download pages before quietly moving their operation onto claude.ai's own platform, turning the trusted domain into a delivery mechanism for credential-stealing malware.
TrendAI™ Research analyzed an intrusion where threat actors used the EtherHiding technique to route ClearFake payload delivery through smart contracts on the BNB Smart Chain testnet. The attack chain ended with two simultaneously deployed stealers, SectopRAT and ACRStealer alongside an on-chain execution tracker that confirmed each victim compromise in real time.
A solo Russian-speaking threat actor ran a 5-year Telegram channel and, starting September 2025, used AI to automate its content, credential theft, and a cryptocurrency fraud scheme targeting American audiences.
Threat actors leveraged Anthropic’s Claude Code npm release packaging error to distribute Vidar, GhostSocks, and PureLog Stealer. This blog details immediate steps organizations can take and best practices to prevent further risk.
A packaging error in Anthropic’s Claude Code npm release briefly exposed internal source code. This entry examines how threat actors rapidly weaponized the resulting attention, pivoting an existing AI-themed campaign to spread Vidar and GhostSocks.

Threat actors exploited Cloudflare's free-tier infrastructure and legitimate Python environments to deploy the AsyncRAT remote access trojan, demonstrating advanced evasion techniques that abuse trusted cloud services for malicious operations.
Through AI-driven code conversion and a layered infection chain involving different file formats and scripting languages, the threat actors behind Water Saci are quickly upgrading their malware delivery and propagation methods across WhatsApp in Brazil.
This blog uncovers an active campaign exploiting CVE-2025-3248 in Langflow versions before 1.3.0 that deploys the Flodrix botnet, enabling threat actors to achieve full system compromise, initiate DDoS attacks, and potentially exfiltrate sensitive data.
Trend™ Research has been tracking an active APT threat actor named Earth Lamia, targeting multiple industries in Brazil, India and Southeast Asia countries at least since 2023. The threat actor primarily exploits vulnerabilities in web applications to gain access to targeted organizations.
Trend™ Research discusses the evolving tradecraft of threat actor Earth Ammit, proven by the advanced toolset used in its TIDRONE and VENOM campaigns that targeted the drone supply chain.
What is PLeak, and what are the risks associated with it? We explored this algorithmic technique and how it can be used to jailbreak LLMs, which could be leveraged by threat actors to manipulate systems and steal sensitive data.
Trend Research discusses the delivery methods, custom payloads, and techniques used by Water Gamayun, the suspected Russian threat actor abusing a zero-day vulnerability in the Microsoft Management Console framework (CVE-2025-26633) to execute malicious code on infected machines.
Trend Research identified Russian threat actor Water Gamayun exploiting CVE-2025-26633, a zero-day vulnerability in the Microsoft Management Console that attackers exploit to execute malicious code and exfiltrate data.
Trend Micro™ Managed XDR assisted in an investigation of a B2B BEC attack that unveiled an entangled mesh weaved by the threat actor with the help of a compromised server, ensnaring three business partners in a scheme that spanned for days. This article features investigation insights, a proposed incident timeline, and recommended security practices.
Trend Micro’s monitoring of the MOONSHINE exploit kit revealed how it’s used by the threat actor Earth Minotaur to exploit Android messaging app vulnerabilities and install the DarkNimbus backdoor for surveillance.
Our researchers identified threat actors exploiting misconfigured Docker servers to spread the Gafgyt malware. This threat traditionally targets IoT devices; this new tactic signals a change in its behavior.
We observed an unknown threat actor abusing exposed Docker remote API servers to deploy the perfctl malware.
